Omniback II V 3.5 and Windows 2000

I have just installed OB II V. 3.5 on my NT Primary Domain Controller(Only Disk and userinterface)and and then upgraded the server to windows 2000 Advanced Server.Now the OmniBack II INET service won't start, the error message is 4294967295 and nothing else!I have tried rebooting the server and I have reinstalled the Disk and user interface with no luck.Please, do anyone know a solution to my problem.I have waited for the Version 3.5, so I could upgrade my PDC to windows 2000.

CAUTION: You should not reinstall your OmniBack II software, so you can keepyour old OmniBack II database and other configuration information. Therefore, in the Setup page of the installation wizard, DO NOT select"Uninstall currently installed version".

Also be aware that Omniback is going to have problems if name resolution is not set up properly (a problem I had when I set up active directory services and NT DNS) and if you are using advanced security services such as proxy/firewalling.
